CC2340R2: icall_api.c vs icall_api_lite.c

Hello Lenio,

Thanks for reaching out.

Could you please confirm which SDK version you are using and the reference project if you are using one? I see HCI_ResetCmd() referenced in hci_tl.h and icall_ble_api.h. You see in our User`s Guide Host Controller Interface API documentation that the HCI_resetCmd() requires hci_tl.h.

BR,

David.

hci_tl.h  is included in both hci_tl.c and icall_api.c. And both functions have calls to HCI_ResetCmd.  So I concluded that there are 2 ways of calling HCI_ResetCmd – one using the icall infrastructure, and the other not using the icall infrastructure. So my question is which one should we use?

 SDK SIMPLELINK-LOWPOWER-F3-SDK, Version: 7.40.00.64

Hello Lenio,

HCI commands from icall_api.c can be used in a icall register task. Please see the following section of the User's Guide: Creating Additional ICall Enabled Tasks about icall register tasks.

The fundamental question is which method is recommended, using the icall structure or not?

Hello Lenio,

I would suggest to use the icall structure for thread synchronization and command status message response through ICall back to the application thread as a result of executing the command. Please see Example ICall Usage.

BR,

David.

A follow up question from the customer is how exactly to switch from "icall lite" to icall? Is this done via configuration in the SDK, Sysconfig, or anything else?
